Oz Clarke and Hugh Dennis are on a mission to revive the good old British pub. Their plan: to scour the British Isles for the best independent drinks, soak up pub culture, and then open a pub of their own, packed full of drinks from England, Ireland, Scotland and Wales. But as they can't agree on what makes for the best of British and Irish booze, they're going to open two bars that will go head to head for one night only. In the final furlong of Oz and Hugh's journey across the British Isles, their pub grand opening is looming. They head to Wales to feed beer to some boozing bovines, risk life and limb convincing local rugby lads to swap their lager for Welsh wine, and seek inspiration from one of the most bizarre pubs in the country - Leintwardine's Sun Inn. After a tour of a Wolverhampton pork scratching factory, Oz fries up an unusual part of the pig's anatomy to produce his own version of this pub essential. Armed with their drinks from across the nation, the journey ends with opening time at their very own pub for one night only. Will the locals prefer Oz or Hugh's drinks?
